On heating rhombic sulphur it melts but viscosity of liquid increases upto `200^(circ)C`and beyond that it dercreases why?

On heating the viscosity of liquid sulphur are

Viscosity of liquids decreases with increase of temprature. Why?

What do you mean by surface tension? State dimension of surface tension. Why the viscosity of a liquid decreases with increase of temperature.
